The Unsubscribe page that came out of the box with Marketo was outdated, and we just updated with a new Landing Page. I've updated the URL under Admin>Email, but the {{system.unsubscribeLink}} token needs to be updated and I can't seem to figure out how to do that. Do you know?

The default unsubscribe message that is in the admin section does not show a link, however it drives to the correct page. The token -{{system.unsubscribeLink}} - drives to a page on our website that does not exist. I was hoping to find an area where I can see the values for all of these system tokens.

I've found that Admin > Email shows this code for the unsubscribe token:

<p style="text-align:center;"><font face="Verdana" size=".5">If you no longer wish to receive these emails, click on the following link: <a href="%mkt_opt_out_prefix%UnsubscribePage.html?mkt_unsubscribe=1&mkt_tok=##MKT_TOK##">Unsubscribe</a><br/></font></p>

But I'm not sure how to edit to direct to another page. If you've found an answer, please let me know, since my question is essentially the same.

In fact, you can do almost everything you want here, including replacing it with a simple

<!-- Comment -->

That will just show nothing and you can use directly the {{system.unsubscribeLink}} token as long as there is a Marketo Landing page with this URL : http://[Your Landing Page Sub-domain]/UnsubscribePage.html

I built a new LP and wanted to plug it into the Unsubscribe Link token, but I was told that I am not able to edit the token whatsoever. So instead, I replaced the token on my Email templates with the new URL. However, if you know of a way to edit the token, I would love to update the URL within the token to use the token in my Email templates, instead of the URL.

You can make sure to delete the default LP terminating in /UnsubscribePage.html and whichever new LP you want to refer to using the System token, you can configure redirect rules under landing pages in Admin so that /UnsubscribePage.html redirects to your new LP if you want to use a unique URL.
